Optimizing the quality of medical care at the end of life has achieved national status as an important health care goal. Palliative care, a comprehensive approach to treating the physical, psychosocial and spiritual needs of patients and their…

Recently, two novel highly selective mu-opioid receptor (MOR) agonists, endomorphin-1 and endomorphin-2, have been isolated from bovine as well as human brains and were proposed to be the endogenous ligand for MOR. Later, endomorphin-1 and…

Previous studies have indicated increased immunoreactivity of the endogenous opioid peptide beta-endorphin in the cerebrospinal fluid (CSF) of infants under 2 years of age with apnea. To assess the role of endogenous opioids in the pathogenesis of…

Previous studies have indicated increased immunoreactivity of the endogenous opioid peptide beta-endorphin in the cerebrospinal fluid (CSF) of infants under 2 years of age with apnea. To assess the role of endogenous opioids in the pathogenesis of…

Worldwide, acute, and chronic pain affects 20% of the adult population and represents an enormous financial and emotional burden. Using genome-wide neuronal-specific RNAi knockdown in Drosophila, we report a global screen for an innate behavior and…

A prospective observational study was performed to evaluate whether the plasma concentration of heat shock protein 72 (HSP72) or β-endorphin is related to clinical signs, blood chemistry, or severity of pain of colic. Seventy-seven horses with colic…

PURPOSE: To determine the levels of beta-endorphin and cortisol in children with multiple injuries and to determine whether there is any difference between and compare the severity of trauma and beta-endorphin and cortisol release as calculated using…

OBJECTIVE: The aim of this study was to examine the possible role of the immune system in the pathophysiology of chronic fatigue syndrome and fibromyalgia syndrome and in the differential diagnosis of depression by investigating changes in peripheral…

This study investigated the involvement of endogenous opioid peptides in mediating cold water swim (CWS) stress-induced antinociception (SIA) in rats with unilateral hind paw inflammation induced by Freund's complete adjuvant (FCA). Following 0.5, 1…

These three neuropeptides were measured at daily baseline values by radioimmunoassay. Stimulated parotid saliva was collected from 31 subjects using a modified Carlson-Crittenden device affixed over Stenson's duct. Methionine enkephalin-like…

Physiological, plasma beta-endorphin and cortisol responses to nasotracheal intubation were studied in 20 distressed infants of median age 0.3 days (range 0.1-23 days) randomized into groups given pethidine 1 mg/kg (n = 10) or alfentanil 20…

Proopiomelanocortin (POMC) is the polypeptide precursor of ACTH. First discovered in anterior pituitary corticotroph cells, it has more recently been revealed to have many other physiological aspects. The fine molecular mechanisms of ACTH…

The timing of the measurement of biological samples (e.g. biomarkers) is not always standardized. Biomarkers are the focus of many recent studies and treatments. The purpose of this study was to determine the timing of the release of beta-endorphin…

Tissue destruction is accompanied by an inflammatory reaction. The inflammatory reaction leads to activation of nociceptors and the sensation of pain. Several mediators are responsible for pain and hyperalgesia in inflammation including cytokines,…

During adolescence the brain shows remarkable changes in both structure and function. The plasticity exhibited by the brain during this pubertal period may make individuals more vulnerable to perturbations, such as stress. Although much is known…

BACKGROUND: Alcohol abuse may involve an altered neuroendocrine response that mediates lymphocyte-derived proopiomelanocortin (POMC) production and inflammation. We investigated POMC messenger RNA (mRNA) expression in human lymphocytes ex vivo and…

Plasma beta-endorphin, cortisol and total opioid-like activities were measured upon arrival at the hospital in ten patients with extensive trauma and in a state of shock and 11 patients with minor injury. Patients in a state of shock had…

BACKGROUND: No study has so far addressed whether differences do exist in the management of cancer-related pain in patients admitted to oncology and non-oncology settings. PATIENTS AND METHODS: A multicentre cross-sectional study in 48 Italian…

BACKGROUND: Sucrose is an effective analgesic for procedural pain in preterm infants. It has been hypothesized that its analgesic effects are mediated by the release of endogenous opioid neurotransmitters such as beta-endorphin. OBJECTIVE: To…

The study of pharmacologically active peptides is central to the understanding of disease and development of novel therapies. It would be advantageous to monitor the fate of bioactive peptides in biological fluids and tissues following their in vivo…

OBJECTIVE: While research has established that pediatric pain is undertreated, it is unclear who should have primary responsibility for its management. This study asks pediatricians who they believe should treat pain and how pain should be assessed…
